' HINGE.-

sPEcIFicA'rIoN forming part of Letters Patent No. 635,368, dated october 24, 189e. Applio ation led May 29, 1899. Serial No. 718,631. (No model.)

To all whom it may concern:

Be tlknown that l, STEPHEN D. ARNOLD, a citizen of the United States, and a resident of New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to improvements in hinges for windows, doors, dro., which are hinged on one edge thereof to a casing and opened by swinging horizontally thereon. If ordinary hinges were used on windows of this kind, the stool or weather-strip which is used to keep out water and wind would prevent the opening of the window in this way.

The object of my invention is to provide a lifting device in connection with a hinge which will allow the use of the ordinary stool or weather-strip and the leaves of which may be separated in the direction of its axis, so that the door or window may be lifted above the stool and swung over it. The particular object of my invention is to produce a simple and novel means of operating the hinge to obtain the desired results. The means by which these objects are accomplished are shown in the drawings, in which- Figure l is a front elevation of a part of a window frame and sash having my improvements applied thereto, the sash being in its closed position. Fig. 2 is a like view showing the sash in its raised position.' Fig. 3 is a detail View showing the hinge and its 0perating mechanism.

In the practice of my invention, referring particularly to the construction and arrangement of parts as shown in the drawings, the frame or casing A is made a little longer or higher than the sash B by an amount equal to or a little greater than the thickness of the weather-strip C. The sash is attached to its frame or casing by a hinge D of ordinary construction, that part of the hinge which is attached to the sash having a shoulder a formed in the knuckle, which engages a shoulder b, formed on the pintle K. The pintle extends beyond the top of the hinge and has at its end the ball c. Fastened to the casing at a distance below the hinge is a step G, which supports the lower end of the lifting mechanism and allows it to be moved horizontally in any position desired. The lifting device consists of a tubular member F, supported at its lower end by thestep G and held in position by the pintle K of the hinge, which is elongated and extends into it. At its lower end the pintle is bent and attened, as at 7.o, said bent portion extending through the slotfin the member F and having suitable means for attachment to a link H. The lug L is preferably made integral with the member F and has pivoted to it the lever J, which is connected with the end of the pin K by the link I-I. When the sash is closed, the handle is in the -raised position shown in Fig. l 0f the drawings. When the window is to be opened, the handle is forced down and the pintle is raised by the link II, attached to the handle, and it in turn raises the part of the hinge attached to the door by means of the shoulders ci and l, respectively. By this construction and arrangement of parts the operating parts of the lifting mechanism are entirely independent of the hinge and exert a force directly in lthe line of the axis of the hinge, thus avoiding all cramping on the hinge and allowing the utmost freedom of movement. In all hinges of this description heretofore designed the hinge itself forms a part of the mechanism by which its leaves are separated. There are serious objections to a construction of this kind, inasmuch as a great strain is brought to bear upon the hinge, and it is apt by continued use to be loosened or bent or cramped and seriously interfere with the proper working of the device.

Another decided advantage which my hinge has over all others is that the operating-lever is rotatably mounted to allow of its being swung out away from the casing while it is being used to raise or lower the sash. Heretofore the operating-levers have been attached to the hinge, so that they lie against the casing or sash while being used, and it has been found to be very inconvenient to operate the hinge under these conditions,especially where the sash has a great weight.

When the parts are in the position shown in Fig. 3 of the drawings, indicating the window closed, the sash is locked against upward movement by reason of the position of the pivots which connect the lever, the link, and the pintle, the intermediate pivot being IOO thrown a little past the line connecting the two outside ones, and thus preventing raising the sash except by means of the handle. So, also, when lthe parts are in the position shown in Fig. 2 the sash is in a position to be swung outwardly, and the lowering thereof by design or accident is prevented except with the aid of the operating lever. By arranging the parts in this way a very effective lock is secured without the addition of any extra pieces.

I claim as my inventionl. The combination with a butt orhinge, of means for separating the leaves thereof in the direction of its axis, said means being rotatably mounted independent of the hinge.

2. Means for separating the leaves of a hinge in the direction of its axis, comprising a pintle and an operating-lever connected byalink, the fulcrum for said operating-lever being rotatably mounted independent of the hinge.

3. In a butt or hinge means forseparating the leaves in the direction of its axis, comprising a pintle and an operating-lever rotatably mounted independent of the hinge, a

a leaf having a shoulder and a pintle engag-Y ing said shoulder,ofatubular member mount; ed below the hinge, the pintle extending therein and having its end bent to project through a slot, and means operatingin connection with the pintle to separate the leaves in the direction of the axis of the hinge.
